Key Words: clinical trials verapamil atenolol hydrochlorothiazide
| Introduction |
|---|
|
|
|---|
The Controlled ONset Verapamil INvestigation of Cardiovascular Endpoints (CONVINCE) Study is a double-blind, randomized, international clinical trial that compares 2 initial treatments for hypertension. One treatment begins with a physician-directed choice of hydrochlorothiazide (HCTZ) or atenolol, and the other treatment begins with controlled-onset extended-release (COER) verapamil (Covera-HS; Searle Pharmaceuticals). The protocol for this study includes an increase in antihypertensive medication (in either dose or number of agents) whenever the BP is not at goal (<140/90 mm Hg).13
The CONVINCE Study therefore provides an excellent opportunity to
examine the extent of BP control in a clinical trial in which forced
titration of antihypertensive medication is recommended whenever the BP
is
140/90 mm Hg.
| Subjects and Methods |
|---|
|
|
|---|
Once an eligible subject provided signed informed consent, site personnel called the IVRS using a toll-free number. With a touch-tone keypad, the caller entered the subjects birthdate, gender, verification of inclusion and exclusion criteria, and confirmation of signed informed consent. The IVRS then generated the blinded treatment assignment, maintaining a continuously updated registry of enrolled subjects and their characteristics. On the completion of enrollment, the data were transferred electronically to the Data Coordinating Center (Coordinating Centers for Biometric Research at the University of Minnesota), which prepared summaries and tables that described the enrolled subjects. Blood pressure data were gathered with the same system during office visits at least every 6 months. Most subjects visited a clinical site at monthly intervals for titration of drug therapy until the BP was <140/90 mm Hg ("End of Titration (EOT)").
Revision of Sample Size
The formal results of the power calculation and related
assumptions have been published.13 The sample size was
increased from 15 000 to 16 600, because the rate of subjects who
discontinued blinded study medication exceeded expectations.
Statistics and Comparisons
The baseline characteristics are reported as mean±SD for
continuous variables. We used
2 tests to
compare the characteristics of participants taking a diuretic
versus a ß-blocker as the standard of care (SOC) choice.

Demographics
The average CONVINCE participant was 65.6±7.4 (SD) years old at
entry, with the women slightly older (66.0±7.6 years) than the men
(65.0±7.1 years). Twenty-five percent of the CONVINCE participants
were between 55 and 59 years old at randomization; 23.7% were between
60 and 64 years old and 22.1% were between 65 and 69 years old, with
declining percentages of older individuals. Fifteen subjects (0.1%)
were
90 years old, 1.0% were 85 to 89 years old, 3.2% were 80 to 84
years old, 9.1% were 75 to 79 years old, and 15.8% were 70 to 74
years old. The average age of CONVINCE subjects varied little among the
participating countries: the lowest mean age was in Bulgaria (62.0
years old), and the highest mean age was in the United Kingdom (67.0
years old).
More women than men were enrolled in CONVINCE: 9300 (56.0%) compared with 7302 (44.0%), respectively. The gender distribution between countries varied more than did the differences in average age. The greatest percentage of enrolled women was in Mexico (68.3%), and the lowest was in the Czech Republic (45.6%).
The race/ethnicity of CONVINCE participants (determined according to the self-report of each subject) was generally representative of the country of origin. Overall, 83.9% of the CONVINCE participants were white, 7.0% were black, 7.0% were Hispanic, 1.6% were Asian, and 0.5% were of "Other" race/ethnicity. These totals reflect the local custom in assignment of race/ethnicity: all participants from Spain except 1 were categorized as "Caucasian"; all 282 Mexican subjects were categorized as "Hispanic." In the United States, 74.2% of those recruited in CONVINCE were white, 13.9% were black, 10.9% were Hispanic, 0.6% were Asian, and 0.4% were of "Other" race/ethnicity; these percentages are very similar to those of the general US population.14 15 Canadian CONVINCE participants also closely matched their national ethnic makeup: 91.8% were white, 6.0% were Asian, 0.8% were black, 0.3% were Hispanic, and 1.1% were "Other."
Treatment for Hypertension
Most participants (83.5%) were taking drug therapy for
hypertension at the time of enrollment. There was, however, a very wide
variation among countries: in Germany, only 33% of the 69 participants
were taking antihypertensive drug therapy at enrollment compared with
97% of the 71 subjects enrolled in the Czech Republic. Because
individuals already on treatment had only to switch from their previous
antihypertensive drug regimen to blinded CONVINCE study medication at
enrollment, it is not possible to determine what level (or stage) of
untreated hypertension they would have had. Their average BP at
enrollment was 148.0±15.7/85.4±9.5 mm Hg. The highest average
on-treatment BPs were found in Germany (159.1/92.4 mm Hg, n=69)
and Sweden (156.6/90.4 mm Hg, n=262); the lowest average
systolic BP was found in the Czech Republic (144.1
mm Hg), and the lowest average diastolic BP was found in
the United States (83.5 mm Hg).
The average BP of the 2701 subjects not taking antihypertensive
medications at enrollment was higher (160.6±13.1/93.9±8.3
mm Hg) than that of the treated individuals, because the protocol
required a BP of
140/90 mm Hg if a subject was not taking
antihypertensive medication. This average BP is similar to that
obtained during the placebo run-in phase in the Antihypertensive and
Lipid Lowering Treatment to Prevent Heart Attack Trial
(ALLHAT)16 but lower than that in the Hypertension Optimal
Treatment (HOT) Study.17
Choice of SOC Treatment
Table 1 shows the percentage of subjects for whom the
investigator chose the diuretic (HCTZ) over the ß-blocker
(atenolol) as the SOC treatment. Despite the concerns of some regarding
the efficacy of ß-blocking agents in preventing
cardiovascular complications in older hypertensive
subjects,18 54% of the subjects in CONVINCE had atenolol
chosen for them by their physician-investigator. The choice between the
diuretic or the ß-blocker showed considerable
country-to-country variation, probably reflecting country-specific
practice preferences. At the extremes, 72.5% of the 823 Spanish
subjects had the diuretic chosen for them compared with only
22.7% of the 71 Slovakian subjects.
As seen in Table 2, the SOC choice varied
by subgroup. Among men, 57.1% had atenolol chosen (over HCTZ) by their
treating physician-investigator compared with 50.8% for women. The
ß-blocker was more commonly chosen than the diuretic in
subjects who had previously had antihypertensive drug therapy (86.5%
versus 80.4%). We do not know whether this represents more
known coronary or other cardiovascular disease
or its risk factors among the men, a reflection of previous adverse
experiences with one or the other agent, or a greater propensity of
diuretics to cause male sexual dysfunction.19 20 21
The physician-investigators tended to prefer the ß-blocker over the
diuretic in younger subjects (55% of those <70 years old) and
the diuretic over the ß-blocker in older subjects (51% of
those
70 years old). This may be in accordance with clinical trial
data in older patients that suggests better outcomes when
diuretics are used compared with ß-blockers.18
Blacks and Hispanics were the only racial/ethnic groups who showed a
significant preference for a specific SOC choice. The
physician-investigators chose HCTZ for 59% of blacks and atenolol for
72% of Hispanics.

Risk Factor Profile
The distribution of traditional cardiovascular
risk factors observed on enrollment of the 16 602 subjects into
CONVINCE is shown in Table 3. Although
only 1 additional risk factor was required for eligibility, nearly half
(49.4%) of the CONVINCE subjects had >1 additional traditional risk
factor. Because individual risk factors increase the future risk of
cardiovascular events more than additively, the 3.2
risk factors present in the CONVINCE study population (including
age in 100% and male gender in 44%) suggest that this cohort is at an
even greater risk for future cardiovascular events than
was shown in other recent studies.16 17 22 23 24 There was,
again, a high between-country variation of the plurality of risk
factors: the countries with the largest number of risk factors were
Poland, Hungary, and Slovakia; the United Kingdom and Sweden enrolled
patients with the fewest risk factors.

BP Control Rates
At randomization, only 20.3% of subjects had controlled
hypertension (<140/90 mm Hg); this increased to
85% (at EOT)
and remained relatively stable at
70% during the first 2 years of
follow-up (Figure 1). At every time
point, control of diastolic BP (to <90 mm Hg) was
achieved in a higher proportion of subjects than was control of
systolic BP (to <140 mm Hg). Because the CONVINCE study
protocol recommended intensified therapy whenever BP was 140/90
mm Hg, many subjects were treated with >1 antihypertensive
medication; this proportion also increased during the time of follow-up
(Figure 2). Subjects not taking
antihypertensive medication at enrollment achieved slightly better BP
control, both at EOT (87.4% versus 84.3% for treated subjects) and
subsequently (69% to 74% versus 64% to 69%). Even at 1 month after
randomization, initially untreated subjects had slightly lower average
BPs (144±16/84±9 mm Hg) than did previously treated subjects
(148±19/85±10 mm Hg).

85%) during forced titration of
antihypertensive medications and then leveled off at
70% during 2.5
years of follow-up. Like many other recent clinical
trials16 17 25 and other studies,26 27 28 the
subjects in CONVINCE were more likely to achieve the
diastolic BP target of <90 mm Hg than the
systolic target of <140 mm Hg, as recommended by Joint
National Committee on Prevention, Detection, Evaluation, and Treatment
of High Blood Pressure (JNC VI)29 and World Health
OrganizationInternational Society of Hypertension (WHO-ISH)
guidelines.30 Compared with other recent hypertension trials, CONVINCE has the highest proportion of enrolled subjects with controlled BPs. At 12 months after randomization, the ALLHAT Research Group reported that 53% of their 14 722 subjects had a systolic BP of <140 mm Hg31 ; the corresponding value for CONVINCE is 71.4%. The Losartan Intervention For Endpoints (LIFE) Study reported that only 25.8% of their 9194 subjects had a systolic BP of <140 mm Hg at 12 months.32
These data have several potential limitations. Subjects who are lost to follow-up or who missed scheduled visits may have poorer control of BP. Also, the better BP control observed during follow-up may be due in part to regression to the mean if participants with poorer BP control on treatment at entry were more likely to be selected for enrollment. The risk assessment for CONVINCE subjects may underestimate the true risk of cardiovascular events because not each subject was systematically assessed for all risk factors. Eligible subjects for CONVINCE needed only to have documented presence of hypertension and 1 additional traditional cardiovascular risk factor. Some subjects are therefore likely to have risk factors that were not identified at randomization, which put them at higher risk than the estimates given earlier. The CONVINCE Executive Committee consciously decided to document only the presence of known risk factors (over, for instance, making a distinction between a "present, absent, or unknown" risk factor), because of the desire to (1) mimic ordinary clinical practice, (2) maximize enrollment and generalizability of the conclusions, and (3) minimize data collection, and cost. Thus, CONVINCE conforms to the "large, simple trial" paradigm.33
These data indicate that a high prevalence of BP control (<140/90 mm Hg) can be achieved in a large hypertensive population if a forced titration strategy is used and medications are provided without charge to motivated subjects by well-trained healthcare providers. These features of CONVINCE may make it easier to achieve a higher level of BP control in this clinical trial than in the general population.
